本人の言葉

  • 肯定“I used Airalo during my super short trip to China last time I was there, and it worked flawlessly. I bought the package beforehand and activated it beforehand as well. When my plane landed I immediately has full access. I believe it is routed through Singaporean servers, so that should also be fine for you I believe?”

  • 否定“I have a different take than most. I was throttled constantly with airalo (I did not buy an unlimited plan, therefore I should not be throttled) in China. When I left Chongqing and arrived in Beijing, not only was I throttled, but my connection dropped constantly as well. (My friend also had airalo and had the same issues on a different phone). Once I arrived in japan, all of these issues subsided.”

  • 否定“Just a heads up I purchased the unlimited connection in China and it’s almost unusably slow for anything. Half the time my apps will timeout the other half they just won’t load. To the point I’ve been stuck on the metro unable to pay. EDIT: support reached out to me but since I left China they are unable to evaluate the issue. So they made it more than right by crediting my account.”

  • 肯定“Just back from China -roamed with my home phone#. partner used Airalo eSim,no Firewall issues -Alipay is everywhere,WeChat rare -setup foreign card on Alipay. Use 2 different cards in case 1 has issues -setup Alipay and Didi with a phone # at home. otherwise it'll ask 4 a China”

    X · @hiddenmarkov1 · 2026-07-27
  • 否定“Airalo is extremely spotty switches to E (Edge) all the time”

    “Okay got Alipay to work Alipay is nice because it acts as a proxy to use other apps like Didi, and Didi won't let me sign up directly, so via Alipay it auto logs you in (kinda like OAuth) Also Meituan app lets me order food from anywhere and apparently it can arrive via a delivery robot Other handy app is Baidu Translate The challenge here is that every Western app like Google Translate, ChatGPT, Google Maps, ChatGPT etc doesn't work at all or doesn't work most of the times, so you kinda have to use the Chinese apps, like DeepSeek Of all my eSIMs my Revolut Global seems to work best, it lets me SOMEHOW open most Western sites fast with no firewall, while Airalo is extremely spotty switches to E (Edge) all the time, I also tried Airalo Hong Kong thinking I could use the Great Firewall hack but that didn't work Whatever Revolut Global eSIM is doing it works amazing in China Yesterday in the subway none of our eSIMs worked though, like we had reception but both of our phones didn't get internet to work. Also nobody spoke any English (which I understand, we're in China) and nobody can read English either So essentially we were illiterate (can't read anything), with no internet, nobody to help us. We tried getting a taxi but they wouldn't take us either because we couldn't communicate Again 99.9% of Chinese don't speak a single word of English, even in 2025, which is OK, it just makes things harder Calling the hotel with my Dutch phone SIM for €5/min ended up being the solution because they could talk to the taxi drivers So yes everything kinda works now! What I see with these travel blogs btw if I write it's difficult I get a lot of replies like "lol fucking n00b!" Which is easy to say but again it's not so easy here But that's also the fun part of China, especially after COVID tourism here from the West appears to have dropped rapidly and Western-Chinese relations have deteriorated rapidly after realizing what a threat China can be in its fast technological development etc. That makes it more interesting as a traveler though because you're the only foreigner almost everywhere I will keep you blogging what I experience next”

  • 質問“Does using an eSIM from Trip.com or Airalo give me 100% certainty that I can bypass the Great Firewall? In other words, will WhatsApp (and potentially other blocked services) definitely work through the eSIM without needing a separate VPN?”

  • 肯定“NordVPN failed for me, so I refunded it. Airalo eSIM via Singapore ran WhatsApp, FaceTime, ChatGPT, Claude, YouTube and X. Still use hotel WiFi for Chinese apps/downloads. Remember: Hotel WiFi = usually behind the firewall International travel eSIM = Western apps still work”

  • 否定“New eSIM still has same stuttering and it’s driving me nuts.”

    “I’m in China at the moment, halfway through my 5 week trip. I’ve used Holafly previously no issues. However this time, I’ve been having issues with social media videos stuttering or not playing at all. I’m from Australia and I can’t watch AFL highlights as the playback just stops and never restarts. Messaging apps are working fine. No difference if I turn VPN on or off. One time just as I arrived in Beijing I lost signal altogether. Couldn’t call a Didi at all. Separate story but I had to use a cab and got scammed when the driver realised I had an issue. Got online with Holafly support and tried everything, eventually they replaced the eSIM saying it’s a VPN crackdown issue and it’s getting more and more common. New eSIM still has same stuttering and it’s driving me nuts. Is it too late to just get another eSIM? I’m not a heavy social media user, I just want to be able to scroll while I’m on the train etc. Thanks everyone for your suggestions.”

I arrived with both Nomad eSIM and silent.link. My intent was to mostly use Nomad Sim, because the price per GB was better, but in the end i asked for a refund and used SilentLink.”

    X · @mick__net · 2026-08-11
  • 肯定“Oh you have to get the Nomad eSIM! It’s the only thing I use in China now after trying dozens of eSIMs. I’m able to use Google, Meta, ChatGPT and Claude without a VPN on it as well. The only thing is you won’t get a Chinese phone number with it. Happy to help verify your WeChat if needed. I toggle between WeChat Pay and AliPay depending on the establishment.”

    X · @JeannaQLiu · 2025-11-26
  • 否定“maybe it has to do with the fact I'm using a 9eSIM adapter? But Nomad uses China Unicom, and my other SIM which is China Unicom shows 5G. Or perhaps with roaming you can only get 4G?”

    Reddit · u/EyeTechnical7643 · 2026-06-25
  • 質問“I am only able to get 4G roaming with those.”

    “Hi, I purchased Nomad and Trip.com eSIM for China. I am only able to get 4G roaming with those. I tried two different phones. The first one is Iphone 11 which doesn't support 5G it seems, but it does support eSIM natively. The 2nd one is a local Chinese OPPO phone that doesn't support eSIM natively (so I used 9eSIM adapter). With this phone I'm able to get 5G with a local China Unicom SIM (shows 5G), but the eSIM still only gave me 4G (shows R4G). I wonder had I used a phone that supports both 5G and eSIM natively would I get 5G? (such as a newer Iphone). Please tell me if you are able to get 5G with your eSIM in China and what kind of phone you are using. Thanks”

    “Unfortunately, after landing in China, the connection was extremely slow and unreliable. I spent about 1.5 hours at the airport just trying to book a DiDi, but the data connection was so poor that the app barely worked. During that process, I used over 200MB of data without successfully booking a ride. In the end, I purchased a different eSIM package through Trip.com, and the connection was immediately fast and stable with no issues at all. Later at the hotel, I contacted Saily support hoping for at least a partial refund, credit, or some form of compensation. However, because I had already used too much data while struggling with the unusable connection, they refused to offer anything.”

We cannot recommend using it here, actually found similar older complaints from a google search so here’s a very recent one. You will struggle to book DiDi, use Amap and other services. It’s lead to my and pretty much all my friends missing taxis due to horrendous connectivity problems. Choose another provider for these areas. Worth noting it was better in Beijing, Luoyang and Xi’An but even on unlimited 5G it’s more like 3G. Onto Chongqing next and not expecting much.”

チェック

買う前 · 到着後

買う前
設定 → モバイル通信に「eSIMを追加」があり、SIMロックなし
ロック端末では渡航用eSIMは使えません。キャリアに確認を。解除に数日かかることがあるので、空港ではなく今週中に。
公式プランページを開く — 価格 · 有効期限 · テザリング · アプリ表記
このページの数字には確認日がありますが、条件は予告なく変わります。購入時点で有効なのは公式商品ページだけです。
自宅Wi-Fiで、搭乗前にプロファイルを入れる
中国本土では販売元サイトやアプリが開かないことがあります。先に入れ、データ回線は到着までOFFに。有効期間は通常、インストールではなく初回接続から始まります。
QR・注文番号・サポートメールをスクショ
クラウドアプリではなく端末内に保存。中国国内ではメールが最も確実なサポート経路です。
使うアプリが中国の電話番号を要求するか確認する
渡航用eSIMはデータだけで、中国の番号は付きません。本土のサービスは認証コード用に中国番号を求めることがあり、旅行者がよく挙げるのはAlipayと12306です。出発前に、自分のアプリのどれが番号を要るか見ておく価値があります。
到着後
eSIMのデータ回線とデータローミングをON
データローミングがOFFのまま、が渡航用eSIMで繋がらない最大原因です。同時に自宅SIMのローミングはOFFにして、想定外課金を避けてください。
2分待っても圏外 → ネットワークを手動選択
設定 → ネットワーク選択 → 自動をオフ → China Mobile / China Unicom / China Telecom を順に試す。都市によってカバーが違います。
アプリが開かない → バックアップに切替。路上で検証しない
ルーティングが変わったか、約束が外れた場合です。出発前に入れたVPNか、予備のeSIMを使ってください。
開通できない → ホテルWi-Fiとメール。アプリではない
注文番号とエラー画面のスクショを添えてメールで問い合わせてください。必要なときに限ってアプリが開かないことがあります。
滴滴や高徳が重い → 回線を手動切替、またはホテルWi-Fi
渡航用eSIMの通信は海外ゲートウェイ経由です。WhatsAppが開く理由であり、中国の現地アプリが遅くなる理由でもあります。ある旅行者は、設定でChina UnicomからChina Telecomに切り替えるまで、検索1回に30秒かかったと書いています。ホテルWi-Fiはファイアウォールの内側なので、現地アプリはそこで軽くなることが多いです。

インストール手順とトラブル対処は 接続方法ガイド にあります。このページは購入前に必要な確認だけです。

FAQ

よくある質問・体験談

プランのルーティングとアプリアクセス条件によります。購入前に商品ページで中国向けプランの説明を確認し、LINEが必須ならバックアップ手段も用意してください。

まず「モバイルデータ通信プラン」がeSIMに切り替わっているか、データローミングがONになっているか確認。次に手動でキャリア検索し、China Mobile / China Unicom / China Telecomに接続。それでもダメな場合は提供元アプリのチャットサポートに英語で問い合わせるのが最速です。

Holaflyの中国向け無制限プランが2026年時点で最も知られています。

動画視聴やテザリングが多い人向けだが、公正使用ポリシー(FUP)により、一定量を超えると速度制限がかかる場合があるため、長期かつ大量通信なら事前に確認を。公式ページ確認(2026年8月6日時点)では3日間US$11.90〜30日間US$73.90(5日間US$20.50・7日間US$27.50・10日間US$36.50・15日間US$50.50)、テザリングは1日1GBまでと案内されています。Nomadにも3日間US$12〜10日間US$33の無制限プランと50GB/45日間US$35のプランがあり、短めの滞在ならこちらも比較対象になります。

基本的には「データのみ」が標準です。日本の電話番号はメインSIMで継続して使えるため、SMS認証や着信は通常どおり受けられます(ローミング料金に注意)。現地の中国番号が必要なら到着後にローカルSIMを別途購入する形になります。

上の比較表では、公式ページで確認できた価格だけを表示しています(2026年8月6日確認)。

最安の入門プランはNomadの1GB/7日間・US$4で、無制限プランは3日間US$12〜10日間US$33、50GB/45日間はUS$35。AiraloとHolaflyは中国向けに無制限プランのみを提供しており、Airaloは3日間US$11.50〜30日間US$69、Holaflyは3日間US$11.90〜30日間US$73.90です。日本円換算は表示せず、購入当日の公式ページで確認してください。

NomadとAiraloは「Asia」プランで本土+香港をカバー、Holaflyは香港を別売りにしています。出張や乗継で両方訪れる場合は、Asiaプランの方が無駄がありません。

iPhone XS〜13は同時に1つのeSIMをアクティブにできます。iPhone 14以降は8つのeSIMを保存し、2つを同時アクティブ化可能。Pixel 7以降も複数eSIM対応です。出張の多い方はメイン+中国出張用にプロファイルを残しておけます。

Nomad・Airalo・Sailyの provider 情報ではテザリング対応が示されることがあります。Holaflyは一部プランで制限される場合があります。仕事用PCをつなぐなら、購入前に対象プランの hotspot / tethering 表記を確認してください。

2026年に中国関連の口コミ167件(公開のオンラインレビューとアプリストア、方向性を示す参考データでYouChina独自テストではありません)を分析した結果、Holaflyが好意的評価63%(73件中)で最も高く、Airalo60%(55件)、Nomad59%(29件)と続き、Sailyは20%(10件、サンプル数が少ない点に注意)と大きく低くなっています。4社とも「現地での接続安定性」が最も多く言及されるテーマで、次いで「有効化のしやすさ」でした。購入前は必ず公式ページの最新情報も確認してください。

通信がいったん国外に出てから戻るからです。渡航用eSIMは本土の基地局に載るローミングで、出口は海外 — Trip.comの公式ガイドはデータが「through overseas or Hong Kong gateways, automatically bypassing the firewall」と書いています。WhatsAppが開くその出口が、滴滴や高徳の検索が毎回通る遠回りでもあります。

対処は上の「到着後」チェックにあります。

eSIMは回線の有無、VPNは特定サイトが開くかを分けて考えます。多くの旅では渡航用eSIMの海外ゲートウェイだけでWhatsApp・Google・ChatGPTは開きます。ホテルWi-Fiやルーティングが外れたときにVPNが要るかは、接続方法ガイドで判断してください。
